Hi, Do you use the master branch ? This commit generates some llvm.R600.store.pixel.color/stencil/depth intrinsics, which were introduced by this commit : http://cgit.freedesktop.org/~tstellar/llvm/commit/?id=761b5e4d7d62f7dc7ac5561f355a1eb0d7dd766e
I think the "unreachable" error means that llvm does not recognise the intrinsic ; if llvm recognised the intrinsic but didn't know how to lower it, there would be a "cannot select" error message.
